Antimicrobial compositions

Abstract

A method for rapid surface sanitization is provided, where the method includes contacting the surface with an effective amount of an antimicrobial composition comprising at least about 50 wt. % of a C 1-6 alcohol, based upon the total weight of the antimicrobial composition; and an efficacy-enhancing amount of a C 1-10 alkane diol.

         46 . The foamable antimicrobial composition of  claim 41 , wherein the diol is present in an amount of at least about 0.05 wt. %, based upon the total weight of the antimicrobial composition. 
     
     
         47 . The foamable antimicrobial composition of  claim 41 , wherein the diol is present in an amount of from about 0.2 to about 0.75 wt. %, based upon the total weight of the antimicrobial composition. 
     
     
         48 . The foamable antimicrobial composition of  claim 41 , comprising from about 0.002 to about 4 wt. % of a siloxane polymer surfactant, based upon the total weight of the antimicrobial composition. 
     
     
         49 . The foamable antimicrobial composition of  claim 41 , wherein said siloxane surfactant comprises one or more of organopolysiloxane dimethicone polyols, silicone carbinol fluids, silicone polyethers, alkylmethyl siloxanes, amodimethicones, trisiloxane ethoxylates, dimethiconols, quaternized silicone surfactants, polysilicones, silicone crosspolymers, and silicone waxes. 
     
     
         50 . The foamable antimicrobial composition of  claim 41 , wherein the fluorosurfactant comprises perfluoroalkylethyl phosphates, perfluoroalkylethyl betaines, fluoroaliphatic amine oxides, fluoroaliphatic sodium sulfosuccinates, fluoroaliphatic stearate esters, fluoroaliphatic phosphate esters, fluoroaliphatic quaternaries, fluoroaliphatic polyoxyethylenes, and mixtures thereof. 
     
     
         51 . The foamable antimicrobial composition of  claim 41 , wherein said foaming surfactant is present in said composition in at least about 0.01 wt. %, based upon the total weight of the antimicrobial composition. 
     
     
         52 . The foamable antimicrobial composition of  claim 41 , wherein said composition further comprises 0.1 to 20 wt. % of one or more humectants, based upon the total weight of the antimicrobial composition. 
     
     
         53 . The foamable antimicrobial composition of  claim 52 , wherein said humectant includes one or more of propylene glycol, dipropyleneglycol, hexylene glycol, 1,4-dihydroxyhexane, 1,2,6-hexanetriol, sorbitol, butylene glycol, propanediol s, dipropylene glycol, triethylene glycol, glycerin (glycerol), polyethylene glycols, ethoxydiglycol, polyethylene sorbitol, glycolic acid, glycolate salt, lactate salt, lactic acid, sodium pyrrolidone carboxylic acid, hyaluronic acid, chitin, and mixtures thereof. 
     
     
         54 . The foamable antimicrobial composition of  claim 41 , wherein said composition includes less than 0.1 wt. % of preservative agents, based upon the total weight of the antimicrobial composition. 
     
     
         55 . A foamable antimicrobial composition comprising:
 at least 50 wt. % of an antimicrobial agent comprising one or more C 1-6  alcohols, based upon the total weight of the antimicrobial composition;   a C 6-10  alkane diol, wherein said C 6-10  alkane diol is present in an amount less than 1.0 wt. %, based upon the total weight of the antimicrobial composition.
